Question

Please someone help me!!

I’m so confused

1.) Circle A has been transformed to Circle B. What is the translation rule for these circles?
A.) (x-2),(y+3)
B.) (x+2),(y+3)
C.) (x-1),(y+4)
D.) (x+4),(y+3)

2.) Circle A has been transformed to Circle B. What is the scale factor of Circle A to Circle B?

Answer 1

(x, y ) → (x + 2, y + 3 )

Explanation:

consider the coordinates of the centres of circles A and B

A (- 1, - 1 ) and B (1, 2 )

- 1 → 1 in the x- direction is + 2

- 1 → 2 in the y- direction is + 3

then translation rule is

(x, y ) → (x + 2, y + 3 )
